COIN-OPERATED LI QUID-RELEASING DEVICE.

SPECIFICATION forming part of Letters Patent No. 416,121, dated November 26, 1889.

Application filed June 20, 1889. Serial No. 314,966. (No model.)

To all whom it may concern.-

Be it known that I, LINNAEUS B. NORCROSS, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Coin-Operated Liquid-Releasing Devices, of which the following is a specification.

My invention relates to apparatus for antomatically delivering liquids in determined quantities, and the objects of the invention are improvement of the devices for separating a determined quantity from the main body of the liquid and of the devices for releasing and discharging such determined quantity of the liquid by the intervention of a coin in the operative releasing devices.

My improvements are illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the devices,

the cap-plate being removed. Figs. 2 and 8 are side elevations from opposite sides, the inclosing-case being shown in section. Fig. 4 is a central verticalsection on the line 90 w of Fig. 1, and Fig. 5 an exterior front view. In said drawings, 1 represents a casing, which may be of circular form, as shown, or other suitable shape for inclosing the operative parts of the improvements.

2 is the back of the casing, and 3 a cap-plate adapted to be removed for inspection of the interior. In an opening in the back 2 is secured a hollow cylinder 4, designed to be inserted and secured water-tight in an opening in the side of a water-vessel A, so that the body of the cylinder 4 will be Within the water-vessel, while the back of the casing 1 will be adjacent to the exterior of the vessel. lVithin the hollow cylinder 4 is placed a water-receptacle 5, occupying the'lower half of the cylinder. The open top of this receptacle 5 is covered by a rubber or other flexible and elastic cover 6, which in its normal position will stand up above the top of the receptacle V 5, so as to nearly fill the cylinder 4 and be capable of downward movement into the receptacle 5 to exhaust the contents of the chamber 7 The inner end of the cylinder 4 is open, while its outer end in the casing 1 is closed and provided with an upper opening 8 and lower opening 9, both the openings 8 and 9 being in communication with the chamber 1.0 of a cylinder 11. In the chamber 10 is a piston 12, adapted to move from a position below the opening 9 to a position above it. The cylinder 4: being in the tank containing the liquid, the flexible cover 6 is first pressed downward, so as to lie very nearly against the sides and bottom of the receptacle 5. The passageways 8, 9, and 10 being open, the liquid will pass into the chamber 7 through the opening 9 until the chamber is filled. The form and arrangement of these parts maybe varied, as desired, and the size proportioned to the quantity of the liquid designed to be released at one operation.

In operation the elastic receptacle-cover 6, when not subjected to the liquid pressure, will occupy the distended position shown in the drawings, and when liquid is introduced into the tank the pressure will collapse the cover 6, and the passage-way 9 1O 8 being open the air will escape from the chamber 7 and be replaced by the liquid passing in through the passage-way 8 1O 9, the expansive force of the cover 6 aiding in the operation of dilating it from its collapsed position.

The piston 12 is 011 a rod 13, that passes through a suitable stuffing-box or packing at the upper end of the cylinder 11, and the end of the rod is secured. to a horizontal plate or arm 14:. To a projecting portion of this arm 1% is connected a vertical rod 15, and in the lower end of the rod is a slot 16, in which operates apin 17, carried on an arm 18, that is attached to the operating-stem 19. On the stem 19, which is supported on a bracket 20, is a suitable handle 21, exterior to the cap-plate 3, so that the turning of the handle 21 to the right (in the direction of the arrow 2) will raise the pin 17 to the head of its slot and move the rod 15 vertically, and with it carry the piston-rod and. piston upward sufficiently to lift the piston above the opening 9. The liquid will then be free to pass from the chamber 7 out of the opening 9, and downward into an outlet-tube 22, to be discharged. On the back of the arm 18 is a pin 23, to which is attached the end of a spring 24, that may be secured to the casing 1. The spring exerts its force to draw the arm outward toward the casing. The pin 23 passes through a slot 25 in a semicircular plate 26, that has its lower end pivoted on a pin 27, secured in the back of the discharge-spout 22. On the upper end of the plate 26 is a coin-receptacle and carrier 28, coinciding with a coin-chute 29 in the top of the casing. I11 the coin-chamber 28 is a slot 30, extending from the front past its center. In line with the center of the coinchamber 28 is a pin 31, carried on a plate 32, that is hinged at 33 to the back 2 of the casing. The plate 32 has its front portion bent laterally at a right angle, and at a suitable point on its edge is a shoulder 34, from which shoulder the edge 35 of the plate extends in an inclined direction upward, and near its top is a second shoulder 36. This plate is held in the position shown in Fig. 1 by the pressure of a spring 37 on its back. In that position the lower edge of the plate 32 bears upon the upper surface of the arm or plate 14 and serves as a stop to prevent the piston from being raised. Upon turning the handle 21 the upward movement of the arm 18 turns the segmental plate 26 on its pivot 27, moving its upper end toward the .pin 31, which passes within the slot 30, if there is no obstruction in the coin-receptacle. If, however, a coin of proper. dimensions has been dropped into the receptacle 28, the movement of the plate will force the coin against the pin 31 and force it backward, turning the plate 32 on its hinge. This movement serves to release the arm 14 from engagement with the lower edge of the stop or plate 32, and permits it to be lifted by the further movement of the handle and -its connecting parts. 'The coin being of proper thickness, the stop-plate 32 will be turned sufficiently on its hinge to move the shoulder 34 out of the way of the course of the arm 14 and will permit the latter to move along the incline 35, thus moving the plate farther to the left until the shoulder 36 is reached and stops further movement of the piston. A post 38 has a slot in its upper portion, through which the angular portion of the stop-plate 32 passes, and it serves as a guide and stop for the plate, and is made to serve as a support for the cylinder 11. The movement of thearm 14 upward to the shoulder 36 lifts the piston 12 sufficiently to open the outlet port 9, and permits the discharge of the fluid from the chamber 7. If, however, the coin introduced in the coin-receptacle .28 be of less than the predetermined thickness necessaryfor operating the parts, then the movement of the plate 32 on its hinge will not be sufficient to carry theshoulder 34 out of the way of the rising arm 14, and its engagement will prevent the piston from being lifted above the outlet-port 9. Thus the introduction into the receptacle 28 of a disk of less thickness than that of the dimension of coin which is designed to operate the device will fail to cause the release of the liquid. The coin in the carrier 28 rests on a fixed platform, and as the carrier is moved forward the coin slides upon the platform until it reaches an incline and falls into a chute, from which it passes into a drawer or receptacle 39.

To prevent the withdrawal of a coin by means of a cord attached to it, there are provided a series of cutters 40, that pass downward between the coin-chute 29 in the case and the carrier 28 when the latter has been moved forward. These cutters may be of any suitable construction for accomplishing the purpose. Those illustrated show an arrangement of cutting-barbs that would engage and sever a cord when an attempt is made to withdraw it. The cutters 40 are carried on shanks 41, fastened to a rocking rod 42. The rod is rocked to make the downward thrust of the cutters by means of a bow 43, that is attached to the rocker, and moved outward by the plate 32 when the latter is turned on its hinge by the movement of the segment-plate 26, and the return rocker movement is accomplished by the action of a spring 44, attached to the rock-shaft and to the casing 1.

In operation, a suitable coin having been deposited through the chamber into the coinreceiver, the handle 21 is turned to the right,

and the piston is thereby lifted past the outlet 9 and the coin carried to the incline, whence it slides into the coin-receptacle 39. The fluid confined in the chamber 7 is permitted to discharge through the opening 9, and when discharged and the handle 21 is released the spring 24 causes the return of the piston to its position below the opening 9, and the chamber 7 is again filled by liquid from the tank passing through the openings 8 and 9 and into the receptacle 5. The buoyancy or resiliency of the cover or diaphragm 6 serves to aid in the flow of the liquid into the receptacle.
